Paradise came up in a conversation with a long time racer of the track recently and they said the "Paradise Track Rules" posted on the website were outdated. Specifically, the roll cage requirement ... I was told that 7.50 was the cutoff for a cage at Paradise (close to an equivalent 11.49 1/4-mile time similar to NHRA requirements). It was my understanding from the website that a car faster than 6.40 requires a cage (basically, anything dipping into the 9's). Could someone please clear this up? What is the requirement at Paradise? Are the "Paradise Track Rules" posted on the site current?
